APPARATUS FOR EJ'ECTING ATOMIZED LIQUIDS.

Application filed August 9, 1926, Serial No. 128,237, and in GermanyMarch 2,1925.

which maybe suspended from a ceiling or the like-with means by which itis moved through the air.

It is another object of my invention to admix a gas or a gas mixture tothe ejected atomized liquid, and, if desired, I may supply such gas ormixture under pressure and utilize its kinetic energy for atomizing andejecting the liquid.

To this end, I provide a cord-like flexible tube, preferably combinedwith 'the cable or cables from which the apparatus is suspended, and Isupply gas under pressure through such tube.

Preferably, the gas admixed is oxygen as by this the air is renewed andits vitiation is counteracted.

The object of my apparatus is first and foremost that of distributingatomized perfumes, to which oxygen or any other as may be admixed asmentioned, this gas being under pressure if desired, in the air of roomsin which there are many persons, theaters, restaurants, etc. It is wellknown that in such rooms the air is gradually but uniformly vitiated.

In reducing my invention to practice, I enclose the liquid to beatomized-which will be referred to as the perfume but obvious ly may beany other liquid-in a. tank in which or on which an engine, forinstance, a motor, may be arranged for moving the apparatus through theambient air. A motor is preferred because its current supply cables mayreadily be combined with the cables on which the apparatus is suspended,and do not interfere with its motion through the air.

In a preferred embodiment of my invention,- the body of the apparatus isshaped like a torpedo or a bomb and encloses a liquid tank, a motoractuating the means for moving the apparatus through the ambient air.

A propeller may be provided for imparting motion to the body and anautomatically controlled rudder may be arranged on the body for movingthe body through the air on a comparatively irregular path so as todistribute the ejected perfume.

-By ejecting oxygen from the apparatus as described its effect is muchimproved for the oxygen not only makes up for the oxygen consumed by thepersons in the room but also, if under high pressure, reduces thetemperature very considerably so that the development of heat in a roomin which there are many persons, is efliciently counteracted.

The means for supplyin oxygen-must stand the high pressure of t at gaswithout interfering with the motion of the body through the air. Oxygenis supplied throug a flexible tube which is preferably inserted in thecable for supplying current to the motor. A rubber tube is insertedbetween the strands of the cable. The strands of the cable and a steelsuspension wire are distributed around the tube. Strands of hemp orother material may be inserted in the spaces between .the strands andthe steel wire. A tape is wound around the combined cable and tube onthe outside and held by strong thread. In this manner a unit is obtainedwhich contains all parts required for the operation of the apparatus andpossesses ample strength for supporting the body.

Means must be provided for permitting the body to turn to all sidesnotwithstanding the oxygen tube connected to the bodyat one end. To thisend, a specially designed bearing is provided. The bearing comprises ahollow shaft the inside diameter of which is equal to the outsidediameter of the flexibletube unit. One end of the unit is securedin oneend of the shaft and the other end of the tube is secured in the otherend of the shaft. The tube ends are inserted gas tight in the shaft butdo not abut within its bore. Even if the two ends. are not in veryintimate contact with the wall of the .bore this does not bring aboutleakage as the surfaces in contact are very long.

Two cylinders of insulatin material are seated on the hollow shaft. T eupper cylinder is secured on' the shaft and the cable strands from thetube unit are inserted in the cylinder and project from its lower face.

The lower cylinder is adapted to rotate about not the hollow shaft andslip rings for the ends of held by a cap nut. A strong eye is secured to.the upper end of the hollow shaft.

In order to atomize and eject the perfume by the jet of oxygen, a tubefor the perfume is provided which opens at the bottom of the body inclose vicinity to the end of the oxygen tube. The stream of oxygen whichissues from the. oxy en tube at high velocity atomizes the per ume fromthe perfume tube. However, to prevent continuous flowing out of theperfume from the tube after the supply of oxygen has been arrested,

.means must be provided for closing the perfume tube to prevent leakageof perfume after the oxygen supply has been shut off. The means areoperated automatically under the influence of the oxygen pressure. The

. oxygen tube is connected to one end of a I cylinder in which a pistonis reciprocating against the action of a spring whlch tends Fig. 3 is adetail plan view illustrating the rudder and the means for operating it.

Fig. 4 is an elevation of a part. of the suspending means for themainbody.

Fig. 5 is a transverse section on the line 55 of Fig. 4.

' Fig. 6 is a longitudinal section of Fig. 4. Fig. 7 is a transversesection through the suspending cable .on the line 77 of Fig. 6; Fig. 81s a detail section of the control valve forming part of the apparatus.

Referring now'to the drawings, 1 is the hollow body of the apparatuswhich re sembles a bomb or tor edo, 2 is the perfume chamber of the b0y, 3 is a filling plug for the chamber, 4 is a transverse partition atthe rear end of the chamber 2, 6 1s a partition at the rear of theartition 4 and providing an intermediate 0 amber 5, and 7 is a motorchamber at the tail end of the body 1, 8 is amotor in the chamber 7, 9is a rearward extension of the motor shaft'which projects from the tailend of the body 1, 20 is a propeller on the outer end of the shaft 9, 21is a pinion on the shaft 9' at the rear of the propeller 20, 22 is areduction gear connected with the pinion, 23 is a disc operativelyconnected with the reduction gear,

24 is a' dog on the disc-and 25 .and 26 are pins on the trunnions 28, 28of a rudder 27.

which is carried on a cage 29 surrounding the propeller 20. 31 is abearing for the shaft of the disc 23 in the cage 29.v The dog 24alternately engages thepins 25 and 26 of the trunnions 28.

Rotation of the motor 8 causes the propeller 20 to rotate and to exert aforward thrust on the bod 1. At the same time, the disc 23 is rotate bits reduction gear 21, 22 and, at each half rotationwhich, due to theconsiderable ratio of the reduction gear, is performed in acomparatively long time,' -at first, as indicated in Figs. 2 and 3, thedog 24 strikes the lower pin 25 of the rudder 27 and causes the rudderto swivel in the direction of the arrow 34, Fig. 3. As soon as the dog24 strikes the upper pin 26 of the rudder the rudder is swung out inopposite direction and the body now turns to the left under the combinedaction of the propeller and the rudder 27. In this manner the body 1 iscaused to move continuously along varying curves and distributes theperfume over a large area.

35 is a sling of strong steel wire bywhich the body 1 is suspended froman e e 36 of a bearing 38, 39, 40 which connects e strands of thecurrent supply cable and aflexible tube 43, 55 for supplying oxygen tothe body, with the latter.

Referring now to- Figs. 4 to 6, a hollow shaft 37 is inserted in twoinsulating cylinders 38 and 39. 40 is a metal cylinder se-" cured to theinsulator 39 and on which the eye 36 is formed or secured. 41 is aflange at the lower end of the sha-ft 37 and 42 is a ball bearing ontheupper face of the flange on which the metal cylinder 40 is carried.

43 is the upper end of a flexible ox gen tube and cable unit which istightly tted into the bore of the hollow shaft 37 and is held by'a capnut 44. An eye orhook 45 is secured to the cap nut by trunnions 46 and aslin 35 passed through'an eye 36 supports the od 1.

Fig. shows the section of the tube and cable unit. 47 are the strands ofthe cable which are distributed about the tube, 48 is a steel wireabsorbing the greater part of the load on the cable, 49 are cords ofhemp or the likewhich may be inserted between the strands 47 and thewire 48.. 51 is a wrapper of tape surrounding the unit and 50 is a layerof strong thread wound about the tape. The unit is slung in the eye 45and thus supports the apparatus.

The strands 47 are conducted out of the tube unit and to bindingposts51" on the upper face of the insulator 38 as shown in Fig. '6.Strands 52 are inserted in the insulator 38 and extend-downwards toconcentric' slip rings '53 in the insulator 39.. 54 are binding posts onthe outside of the insulator 39, to which are connected cables 32 alongthe sling 35. The lower end of theoxygen' inder at a point intermediateits ends, 59 is a piston having a circumferential groove 62 and adaptedto reciprocate in the c linder against the action of a spring 60, 5 isan oxygen nozzle connected to the cylinder at a 'point swept by thepiston, and 66 is the corton to register with the perfume pipe 61 andthe perfume nozzle 66 and uncovering the passa e through the nozzle 57.Perfume now ows from the nozzle 66 andis atomized by the jet of'oxygenfrom the nozzle 57.

In the position illustrated the piston blocks both nozzles 66 and 57 andprevents leakage of perfumefrom the nozzle 66.

i It will be understood that in'this manner oxygen under high pressureis supplied to the body 1 without interfering with its motions as thelower end 39, 40 of the bearing is perfectly free to turn-on the hollowshaft 37 with the body and the sling35 and the tube 55. a r
